Control Strategies

A greenish beetle with cream or yellow bands across the wing covers, common in the southern United States and tropics. Adults chew leaves and transmit bacterial wilt in cucurbits; larvae feed on roots and tubers.

About 6–7 mm, longitudinal bands may be partial; looks similar to striped cucumber beetle but banding pattern differs. Larvae are thin white wireworms with dark heads.

Organic Control Methods

Prevention

Use floating row cover until pollination; delay planting slightly to pass early adult peak where feasible.

Biological Controls

Beneficial nematodes (Steinernema spp.) against soil larvae; Microsporidian pathogens occur in populations.

Cultural Practices

Trap crop with preferred squash or blue hubbard; rotate away from cucurbits; clean debris to reduce overwintering.

Mechanical & Physical

Sticky traps or yellow cups with soapy water; hand-pick adults evenings.

Organic Sprays

Kaolin clay on leaves reduces feeding; spinosad or neem for adults—reapply after rain.
